He says: what is the ruling on cutting off family members if they practice sorcery?

I say these people must be cut off if they practice sorcery, and you should not live with them.

If they truly practice sorcery, but if it is just suspicion or imagination, then no. But if it is certain, then he should leave, he should not live in that house if he is able.

He should live outside, yes.

And he should take with him anyone from the family who does not practice sorcery and take them out.
